Abstract (en)

[origin: WO2014114860A1] The present invention relates to a microscope having a multimode local probe comprising: a resonator (1); a first electrode (9) and a second electrode (8); an excitation source suitable for generating mechanical resonance in the resonator; a metal tip (4) attached to the resonator; means allowing relative movement between the local probe and a sample, which can move the end of the tip so that it is at a distance Z between 0 and 100 nm from the sample; and means for detecting at least one electrical signal representing shear forces on the terminals of said electrodes (8, 9). According to the invention, said metal tip (4) is electrically connected to said second output electrode (9), and the microscopy apparatus comprises means for amplifying and filtering the signals relative to the shear forces and to the tunneling current in a single electronic circuit; and means for controlling the distance Z between the end of the tip and the surface of the sample.
